Avalanche.Identity

Avalanche.Identity is a class library for managing object and type identities across type schemas in a generalized interface.

The design principle is that identity is deconstructed into parts. Parts can then be processed in case-specific way. The most typical case is comparison of context-free and context-dependent identities.

// Get Type
Type type = typeof(System.Collections.Generic.List<System.String>);
// Create type identity
IIdentity id = IdentityAccessors.Default.TypeName.Create(type);

"List`1" → "Generic" → "Collections" → "System" → "6.0.0.0" → "System.Private.CoreLib" → 7cec85d7bea7798e → "neutral"
└── "String" → "System" → "6.0.0.0" → "System.Private.CoreLib" → 7cec85d7bea7798e → "neutral"

Identities are deconstructed into linked list. Typical identities have namespaces, which constitute a trie structure when identities are interned.

Quick bits

Identities.CreateName() creates name identity.

IIdentity identity = Identities.CreateName("Name");

Identities.CreateNamespace() creates namespace identity.

IIdentity identity = Identities.CreateNamespace("Namespace").AppendName("Name");

.Print() prints into parseable string.

string name = identity.Print();
